MiniBooNE and The Status of Sterile Neutrinos

Abstract - Recent results from short baseline neutrino experiments have reignitedinterest in ~1 eV sterile neutrinos. I will present the latestresults from MiniBooNE and review anomalies in other short baselineneutrino experiments. In an attempt to resolve the tension betweenthese datasets and constraints from other experiments, I willintroduce sterile neutrino models which include one, two, and threeadditional neutrino states. The results of global fits show thatsterile neutrino models can help to resolve some but not all of thetension among the datasets. Ultimately, additional experiments areneeded to determine if recent short baseline anomalies are due to theexistence of sterile neutrinos. >
